The sum of two consecutive numbers is n+1. What are the numbers?

asked by john
  1. let the first be x
    then the next is x+1

    x + x+1 = n+1
    2x = n
    x = n/2

    the numbers are n/2 and n/2+1 or (n+2)/2 , where n is an even number.

    e.g. let n = 6
    then x = 3, and (n+2)/2 = 4
    their sum is 7 OR n+1 which is also 7
